As an engineer in the Applied AI Engineering (AAI) organization, you will apply your deep domain expertise, engineering skills, and sound judgment to make our frontier LLMs best-in-class on real-world tasks. You will identify gaps in current model capabilities and build the complex systems, agentic pipelines, reinforcement learning environments, and evaluations that generate high-quality training signals. Working closely with Meta Superintelligence Labs, AAI contributes to advancing Meta's frontier models and AI products.We deliberately operate like an early-stage company: a flat, AI-native organization with light processes, wide scope, and fast decisions. We are looking for engineers with strong technical foundations and AI fluency who are energized by ambiguity and by advancing Meta's frontier AI capabilities.\nResponsibilities\nCollaborate with cross-functional teams (product, design, operations, infrastructure) to build innovative application experiences. Implement custom user interfaces using latest programming techniques and technologies. Analyze and optimize code for quality, efficiency, and performance, and provide feedback to peers during code reviews. Set direction and goals for teams, lead major initiatives, provide technical guidance and mentorship to peers, and help onboard new team members. Architect efficient and scalable systems that drive complex applications. Identify and resolve performance and scalability issues, and drive large efforts to reduce technical debt. Work on a variety of coding languages and technologies. Establish ownership of components, features, or systems with expert end-to-end understanding.\nQualifications\n8+ years of programming experience in a relevant language OR 4+ years experience with a PhD Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience Experience utilizing data and analysis to explain technical problems and provide detailed feedback and solutions Demonstrated experience driving change within an organization and leading complex technical projects 6+ years relevant experience building large-scale applications or similar experience Experience improving quality through thoughtful code reviews, appropriate testing, proper rollout, monitoring, and proactive changes Experience in programming languages such as C, C++, Java, Swift, or Kotlin, and scripting languages such as Python, Javascript, or Hack Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements) Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews) Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies Demonstrated ability to solve ambiguous problems, and propose process and technical improvements in a dynamic, fast moving organization Experience designing automated pipelines that generate synthetic training data or evaluation tasks Experience building verifiable environments and quality controls for AI training data, including test harnesses, automated graders, contamination detection and taxonomy
